Folk Punk/Rock. Older stuff sounds like old Against Me!, newer stuff is a bit more unique and they released one of the best albums so far this year. It's just a matter of if you can dig the vocalist or not.

he did a good job.
I can't say how good they are live though, due to the amount of instruments on the cd, but I'd definately be interested in seeing 'em. Anyone know?
